Forgiveness Is the Attribute of the Strong:Nonadherence and Regimen-Shortening in Drug-Sensitive TB

RATIONALE: 'Forgiveness' charts the ability of a drug or regimen to withstand non-adherence without negative clinical consequences. OBJECTIVES: We aimed to determine the influence of regimen length, regimen drugs and dosing, and when during treatment non-adherence occurs on the forgiveness of anti-tuberculosis regimens. METHODS: Using data from three randomised controlled trials comparing experimental four-month regimens for drug-sensitive tuberculosis with the standard six-month regimen, we used generalised linear models to examine how the risk of a negative composite outcome changed as dose-taking decreased. The percentage of doses taken and absolute number of doses missed were calculated, during the intensive and continuation phases of treatment, and overall. A mediation analysis was undertaken to determine how much of the association between intensive phase dose-taking and the negative composite outcome was mediated through continuation phase dose-taking. MEASUREMENTS AND MAIN RESULTS: Forgiveness of the four-month and six-month regimens did not differ for any treatment period. Importantly, four-month regimens were no less forgiving of small numbers of absolute missed doses than the six-month regimen (e.g. for 3-7 missed doses versus no missed doses (baseline), six-month regimen adjusted risk ratio 1.65 (95% confidence interval 0.80-3.41) and four-month regimens 1.80 (1.33-2.45)). No four-month regimen was conclusively more forgiving than another. We found evidence of mediation by continuation phase dose-taking on the intensive phase dose-taking and negative composite outcome relationship. CONCLUSIONS: With the current appetite for, and progress towards, shorter drug-sensitive tuberculosis regimens worldwide, we offer reassurance that shorter regimens are not necessarily less forgiving of non-adherence. Given the importance of continuation phase adherence, patient support during this period should not be neglected

What causes treatment failure - the patient, primary care, secondary care or inadequate interaction in the health services?

<p>Abstract</p> <p>Background</p> <p>Optimal treatment gives complete relief of symptoms of many disorders. But even if such treatment is available, some patients have persisting complaints. One disorder, from which the patients should achieve complete relief of symptoms with medical or surgical treatment, is gastroesophageal reflux disease (GERD). Despite the fact that such treatment is cheap, safe and easily available; some patients have persistent complaints after contact with the health services. This study evaluates the causes of treatment failure.</p> <p>Methods</p> <p>Twelve patients with GERD and persistent complaints had a semi-structured interview which focused on the patients' evaluation of treatment failure. The interviews were taped, transcribed and evaluated by 18 physicians, (six general practitioners, six gastroenterologists and six gastrointestinal surgeons) who completed a questionnaire for each patient. The questionnaires were scored, and the relative responsibility for the failure was attributed to the patient, primary care, secondary care and interaction in the health services.</p> <p>Results</p> <p>Failing interaction in the health services was the most important cause of treatment failure, followed by failure in primary care, secondary care and the patient himself; the relative responsibilities were 35%, 28%, 27% and 10% respectively. There was satisfactory agreement about the causes between doctors with different specialities, but significant inter-individual differences between the doctors. The causes of the failures differed between the patients.</p> <p>Conclusions</p> <p>Treatment failure is a complex problem. Inadequate interaction in the health services seems to be important. Improved communication between parts of the health services and with the patients are areas of improvement.</p

Testing for an effect of a mindfulness induction on child executive functions

Several sessions of mindfulness practice can exert positive gains for child executive functions (EF); however, the evidence for effects of a mindfulness induction, on EF for adults, is mixed and this effect has not been tested in children. The immediate effect of an age appropriate 3-min mindfulness induction on EF of children aged 4–7 years was tested. Participants (N = 156) were randomly assigned to a mindfulness induction or dot-to-dot activity comparison group before completing four measures of EF. A composite score for EF was calculated from summed z scores of the four EF measures. A difference at baseline in behavioural difficulties between the mindfulness induction and comparison group meant that data was analysed using a hierarchical regression. The mindfulness induction resulted in higher average performance for the composite EF score (M = 0.12) compared to the comparison group (M = − 0.05). Behavioural difficulties significantly predicted 5.3% of the variance in EF performance but participation in the mindfulness or comparison induction did not significantly affect EF. The non-significant effect of a mindfulness induction to exert immediate effects on EF fits within broader evidence reporting mixed effects when similar experimental designs have been used with adults. The findings are discussed with consideration of the extent to which methodological differences may account for these mixed effects and how mindfulness inductions fit within broader theoretical and empirical understanding of the effects of mindfulness on EF

All non-adherence is equal, but is some more equal than others? TB in the digital era

Recent advances in digital adherence technologies (DATs) have renewed discussion on how to best address non-adherence, as well as offering important information on dose-by-dose adherence patterns and their variability between countries and settings. Previous studies have largely focussed on percentage thresholds to delineate sufficient adherence, but this is misleading and limited, given the complex and dynamic nature of adherence over the treatment course. Instead, we apply a standardised taxonomy- as adopted by the international adherence community- to dose-by-dose medication-taking data, which divides missed doses into a) late/non-initiation (starting treatment later than expected/not starting), b) discontinuation (ending treatment early), and c) suboptimal implementation (intermittent missed doses). Using this taxonomy, we can consider the implications of different forms of non-adherence for intervention and regimen design. For example, can treatment regimens be adapted to increase the ‘forgiveness’ of common patterns of suboptimal implementation to protect against treatment failure and the development of drug resistance? Is it reasonable to treat all missed doses of treatment as equally problematic and equally common when deploying DATs? Can DAT data be used to indicate the patients that need enhanced levels of support during their treatment course? Critically, we pinpoint key areas where knowledge regarding treatment adherence is sparse and impeding scientific progress.https://doi.org/10.1183/23120541.00315-20206pubpub

Career Resourcing and the Process of Professional Emergence

We theorize a career resourcing process that explains how individuals can create a new profession. Using historical archives, we trace the emergence of health services research as a new research profession through the career actions of early practitioners. We find that career resourcing can lead to the institutionalization of a new profession by: 1) a process of accretion, where people pursuing fulfilling careers generate resources that contribute to institutionalization, or 2) institutional work to deliberately build the professional community and infrastructure. We contribute to research on institutional change by specifying career actions that can lead to the institutionalization of a new profession, and by developing theory that accounts for the motivations and the means of individuals to act in ways that result in the institutionalization of a new profession

A Comparative Analysis of Mitochondrial Genomes in Coleoptera (Arthropoda: Insecta) and Genome Descriptions of Six New Beetles

Coleoptera is the most diverse group of insects with over 360,000 described species divided into four suborders: Adephaga, Archostemata, Myxophaga, and Polyphaga. In this study, we present six new complete mitochondrial genome (mtgenome) descriptions, including a representative of each suborder, and analyze the evolution of mtgenomes from a comparative framework using all available coleopteran mtgenomes. We propose a modification of atypical cox1 start codons based on sequence alignment to better reflect the conservation observed across species as well as findings of TTG start codons in other genes. We also analyze tRNA-Ser(AGN) anticodons, usually GCU in arthropods, and report a conserved UCU anticodon as a possible synapomorphy across Polyphaga. We further analyze the secondary structure of tRNA-Ser(AGN) and present a consensus structure and an updated covariance model that allows tRNAscan-SE (via the COVE software package) to locate and fold these atypical tRNAs with much greater consistency. We also report secondary structure predictions for both rRNA genes based on conserved stems. All six species of beetle have the same gene order as the ancestral insect. We report noncoding DNA regions, including a small gap region of about 20 bp between tRNA-Ser(UCN) and nad1 that is present in all six genomes, and present results of a base composition analysis
